The security barrier Yezh – Russian Federation patent №93039

Usage: for the manufacture of security barriers, which include thorny elements used as barriers to prevent the unauthorized entry of people and animals on sensitive sites. The inventive protective fence consists of a set of autonomous protective elements, each of which includes many elements, fixed on the substrate. Affecting member comprises a piercing and cutting hard tapered pins of different lengths are attached symmetrically or randomly, and preferably radially to the base. The base is formed as a convex continuous solid structure, such as a spherical or cylindrical segment. To increase the weight of the substrate, its inner cavity can be filled with any heavy material, such as poured concrete. Pointed pins may be provided with additional striking elements in the form attached to them in a random order or tapered symmetric branches of different lengths, or spikes, or barbed tape wrapped. The security element may be provided with positive drive rotation of its base. Technical advantages: increased protective properties; extension of the scope; increasing destructive properties; the complexity of the unauthorized removal; the possibility of self-installation; increase the deterrent effect; the inability to remove elements; improving the efficiency and reliability of the protection of sensitive sites.

The invention relates to the field of building security installations and systems, which include barbed-cutting elements, and can be used for the manufacture of security barriers used to prevent unauthorized access of people and animals on sensitive sites.

Known fence to protect against thieves and other large animals, which contains a horizontal crossbar from a corner, attached to a vertical column and vertical fence welded to the bars indicated at regular intervals. Poles and fence made of metal rolling straight dihedral angles. The upper ends of the pillars and are fences length each right dihedral angle to form a stud at this end [see Russian Federation patent №2296203 class E04N 17/14 published in 27.03.2007].

The main drawback of this sampling is insufficient protective properties against thieves. This disadvantage is explained as follows. Since the fence has a flat structure and fence installed at regular intervals, you can easily take hold of the horizontal crossbar between fence and easy to climb over the fence without damaging of thorns. Thus, the famous fence is effective only as a barrier for large animals, but is not effective as a protective barrier against thieves.

The closest in its essence and attainable effect, taken as a prototype, is a protective barrier "Dikobraz", which consists of a set of autonomous spherical protective elements, each of which includes numerous elements, made in the form of reinforced twisted barbed tape attached (wound) to based suite in the space frame. The space frame is formed in the shape of a sphere formed by coils of wires meridional and equatorial ring installed inside the coils of wires meridian. Meridian wire windings bonded to each other at the poles of the sphere and the equatorial ring. The protective barrier erected as follows. Ready first spherical protective element is attached to a vertical or inclined stand at the poles of the sphere and on-site security abroad. Further, adjacent to the first spherical protective member disposing the second, third and so on similar spherical protective elements over the whole length of the safety barrier, forming a protective boundary [see Russian Federation patent №2272113 class E04N 17/04 published in 20.03.2006].

The main disadvantage of this significant security barrier is the low rigidity of its security features. Since the spherical base is made of a relatively thin wire, it is easy to deform (flatten), thereby forming a free passage for the smooth overcome the security barrier, which reduces the reliability of the protection of sensitive sites.

Another significant disadvantage of the given security barrier is the high complexity of manufacturing as its own spherical elements and their mounting on the guard turn: after all, each of them must somehow attach, and for this you must first install and plug the fasteners on the future of the turn. The process of installation is not safe for installers: a high probability of injury in the course of manipulating a protective spherical element during its attachment to the fastener. Making the security element involves prefabrication of the spherical bases, followed by winding it barbed tape that has to repeatedly pass through between the meridian wires basis that, firstly, laborious and lengthy in time, and, secondly, it is unsafe: when such a complex manipulation hands barbed tape high probability of employee injury. That is, the structure of the known safety barrier is not technological.

The third major shortcoming is the inability of the protective fence construction of its operational, if necessary, for example, for closing the passage. The presence of this lack is explained as follows. The security element has a spherical shape that is unstable. If such a shielding member set on the ground or pavement, it winds may even move it, if it is not fixed. In some cases, such as in mass violations of public order, a sports fan or a militant youth, there is a need for operative blocking the road or sidewalk, the break in the fence, etc., the use of spherical protective elements known protective fence is virtually impossible, because it will take a lot of time for fixing each of them to the road surface, which in the case of force majeure is not there. This circumstance is due to structural imperfections protective elements narrows the scope of the known protective barrier.

Another significant disadvantage of the known security barriers are its low technical-strength characteristics. The presence of this shortcoming is due to the following. Protective barrier member made of a barbed tape wound on a wire substrate. Since the belt is made of sheet metal or a wire of small diameter, it can be easily cut, for example, conventional metal shears or snack conventional forceps, thereby violating the integrity of the protective element and thus forming a free passage in the security fence for unimpeded penetration on modal facility, which reduces the reliability of the protection of sensitive sites.

The basis of the utility model the task of reducing the complexity of manufacturing the security barriers while increasing technical and operational characteristics thereof, extending the scope and reliability of the protection of sensitive sites due to changes in the structure of the security element by performing elements hard and framework – in the form of a convex solid massive construction, which symmetrically or randomly and radially mounted said hard elements.

This object is achieved in that the protective fence, which consists of a set of autonomous protective elements, each of which includes many elements, fixed on the basis of, as suggested affecting member comprises a barbed tape pins of different lengths are attached symmetrically or predominantly chaotically and radially to the base formed as a convex continuous solid structure, such as a spherical or cylindrical segment.

To increase the weight of the substrate, its inner cavity can be filled with any solid material, such as poured concrete.

To enhance the damaging effect sharpened rigid pins may be provided with additional striking elements in the form attached to them in a random order or tapered symmetric branches of different lengths, or spikes, or barbed tape wrapped.

As the element, aggressiveness for increasing or frightening effect, the security element may be formed by forcibly rotating the rotary drive of its base. It's enough to place at the basis, for example, the electric motor and the basis of the security element on the spine implant of the motor. Forced rotation of barbed sharpened pins visually increases the aggressiveness of the security element and is used when an attempt to break into the custodial facility or to overcome the overlapped portion of the road becomes apparent.

Due to the fact that the bottom of the base has a flat bearing pad is not needed, additional fastening when placed on the ground or on the road surface, thus it can be quickly installed at any desired location without attachment reliably block the passage.

Thanks to cutting-piercing elements are arranged radially relative to the substrate, it becomes inaccessible to capture arms for the purpose of unauthorized removal of the protective element to open the passage. Prevents unauthorized removal of the protective element also contributes to the large mass of its foundations.

Thanks to cutting-piercing elements in the form of quite thick, and thus hard tapered pins cannot be deleted (snap or cut) by means of conventional techniques, for example, scissors, metal or conventional wire-cutters.

Thus, the proposed protective barrier achieves a technical result of the task at hand, namely the improvement of technical and operational characteristics of the consumer or, in particular, protective properties, as well as the expansion of the field of use.

Further essence of the utility model will be explained in conjunction with illustrative pictures, showing:

• Figure 1 – a protective element, a plan view;
• Figure 2 – the same, side view.

Embodiments of the sharp-barbed elements:

• Figure 3 – pin pointed with sharp spikes;
• Figure 4 – sharp pin, coiled barbed tape;
• Figure 5 – pin pointed with sharp branches.

The proposed protective fence consists of a set of autonomous protective elements, each protective element includes multiple hitting elements formed as piercing and cutting hard tapered pin 1 of different lengths attached symmetrically or randomly, and preferably radially to the base 2 made in the form of convex solid massive structure, for example, a spherical or cylindrical segment. Production of substrate 2 in the form of a flat segment provides a bearing surface which confers resistance to the security element. To increase the weight of the substrate 2, its inner cavity can be filled with any heavy material, such as poured concrete 3. To enhance the damaging effect of rigid pointed pins 1 may be provided with additional striking elements in the form attached to them in a random order or a symmetrical or sharp pin 4 wound barbed tape 5 or 6 provided with sharpened branches of different lengths.

The proposed protective barrier is erected as follows.

Ready first security element is secured to a vertical or inclined for reception base by any known method and thus set in place the security boundary. Further, adjacent to the first protective member disposing the second, third and so on similar protective elements over the whole length of the safety barrier, forming a protective boundary. When placing the protective elements on the ground, they do not need fixing. Needless to say, the protective elements may be located on the guard turn in several rows. With a significant weight of the protective elements, it is difficult to pull security abroad, grasping the hands pointed pin 1. In addition, the presence of the tapered pins 1 other damaging elements in the form of studs 4, 5 ribbons of barbed or pointed branches 6 general preclude the possibility of their girth hands that still more increases the protective properties of the proposed protective barrier.

Since the mass of the carrier 1 is much higher than the total weight of the tapered pin 2, when you try to turn the protective element, it will turn back on their own based on 1 down. That is the proposed construction of the protective element of self-setting.

Essential difference of the proposed technical solutions from the prior art, is that the protective element is a solid support with radially extending from it pointed spikes of different lengths, which are equipped with the additional striking elements in the form of spikes, claws or branches barbed tape. These differences, together, preclude any possibility of overcoming the security element due to the impossibility for him to grasp, not to mention the fact that you can climb through it. This circumstance allows us to consider the proposed protective barrier almost insurmountable. None of the prior art security barriers cannot have them because the mentioned properties of the protective elements have a small mass, or is easily deformed due to the insufficient stiffness.

The proposed technical solution tested in practice. The security barrier "Yezh" does not contain any elements and components that cannot be replicated at the present stage of development of science and technology, in particular, the production of safety barriers and security barriers is therefore acceptable for industrial applications, has the technical and other advantages over known such technical solutions for the proposed design features of the security element, which confirms the possibility of achieving a technical result of the claimed subject, in certain sources of information not found similar security barriers with these essential features of the proposal, and therefore is considered to be those that can get legal protection.

The main technical advantages of the proposed technical solutions, in comparison with the prototype are as following:

• Increase the protective properties due to the fact that the protective element comprises a rigid elements radially extending from the massive foundations;
• Expanding the application due to the fact that the base has a mounting pad at the bottom;
• Increasing destructive properties by equipping tapered pins additional striking elements;
• The complexity of the unauthorized removal of security element to security abroad because of its considerable weight;
• The possibility of self-installation of the security element of the significant differences mass base and tapered pins;
• Increasing deterrent effect due to the forced rotation of the security element;
• The inability to remove (cut, bite) elements due to their performance relatively thick;
• Improving the efficiency and reliability of the protection of sensitive sites due to the inability to overcome the security barriers.

Social benefits from the implementation of the proposed technical solution are compared with prototype, obtained by improving the protection of sensitive sites and expand the use of security barriers.

The economic effect of the introduction of the proposed technical solution is compared with the prototype, obtained by simplifying the technology of manufacturing and installation of security barriers, the use of common materials in the construction and, consequently, a decrease in its value.

After the description of the proposed security barrier, specialists in the given area should be apparent that all of the above is merely illustrative, and do not limit, having been presented by this example. Numerous possible modifications of the security element, in particular, the number, size, options of the tapered pins on the basis of size, weight and shape of the latter may vary in different ratios, and, of course, within the scope of one of ordinary and natural approaches in the given area and considered to be within the scope of the technical solutions.

The quintessence of the proposed technical solution is that the protective element is a massive base with rigid radial striking elements which can be fitted with striking elements, and these circumstances together, allow purchase proposed protective fence mentioned and other advantages. Change and use of only the individual components of the protective fence, naturally limits the range of the benefits listed above, and cannot be considered a new technical solution in the field of knowledge, since otherwise, similarly to the protective fence, no longer require any creativity of designers and engineers, and therefore cannot be considered the result of their creative activity or a new object of intellectual property to be protected enjoying the protection document.
